    I don't have a link to a good PNG heightmap, but I used Wilbur to read the ETOPO2 data and write out an equal-area 8-bit heightmap based on that data set. The histograms for each area shown below. The hump to the left is the oceanic abyssal plain and the big spike is the coastal plain/continental shelf. A straight histogram on the Plate Caree projection of the original ETOPO2 data set has some artifacts as shown in the second one (that hump off to the right in the plate caree projection is due to polar distortion for Antarctica, most likely).

    You really don't need to worry about the nasty details of world building, as almost anything can get explained away by hand-waving. The real trick is to realize the polar distortion that occurs. Because of that, I like to work on base world maps using a vector tool to get the shapes correct when mapped to a sphere, otherwise the whole "greenland looks bigger than south america" problem starts to rear it's ugly head!

    I think that is why many of the scifi mappers like to work on triangular/hex based projections of planets...

    So the focus area is meant to be Europe-like in location/climate?

This is some far over my head atm I couldn't even do a simple layout in one of the map grab sections and be at the right scale LOL. this has been an enjoyable read tho.
